Title: Improved Method of Marking Components.
Inventor: DAVY JOHN RUPERT
IPC: B23K26/18
Filed: 1965-08-31
Abstract: 1,155,272. Optical apparatus. BARR & STROUD Ltd. Aug.30, 1966 [Aug. 31, 1965; May 20, 1966], Nos. 37237/65 and 22511/66. Heading G2J. [Also in Division H1] A graticule or other mark is formed on an optical material by coating the latter with a light absorbing substance and either directing a laser beam thereat through a mask or focusing the laser beam to a small diameter and moving the beam relative to the coated material. The mask may be formed by crossed wires so that the laser beam vaporizes the whole coating except at lines corresponding to the crossed wires. Alternatively the mask may have an aperture corresponding to the desired mark, the surface where the beam impinges then being treated to render it opaque and the remainder of the coating removed, or the coated surface may be the phosphor of an image converter so that where it is removed by the laser beam forms the desired graticule when the converter is in use. A graticule may be similarly formed on the tube of a television camera. To form a reduced graticule a reversed telescope may be inserted between the mask and the optical material. The produced graticule may be protected by a thin cover glass.

Patent GB-499417-A (GB)
Title: Process of obtaining glycerol and glycerol-like products
IPC: C07C29/00
Filed: 1937-08-17
Abstract: Glycerol and glycerol-like products are obtained by treating with hydrogen a carbohydrate containing a larger number of carbon atoms than the product obtained, in the presence of a copper aluminate catalyst.  The catalyst is obtained in known manner by heating oxide-producing compounds of copper and aluminium to 750-1100 DEG  C. until an acid-insoluble cocoa-coloured product results.  It may be promoted by an addition of alkali.  According to an example 10 parts of sucrose, 0,75 parts of catalyst with a small addition of sodium carbonate, and 10 parts of methanol are treated with hydrogen at about 1700 lb. per sq. in. at 250 DEG  C. The product contains 45,8 per cent of propylene glycol, 21,5 per cent of glycerol and 6,8 per cent of less volatile glycerol-like products.  In another example dextrose is similarly treated.

Oxazolone derivatives of the above formula exemplified as suitable as fungicides are 2-methyl-4-benzilidene-oxazol-5-one, 2-methyl-4-(21-nitrobenzilidene) - oxazal - 5 - one, or 2 - (21 - furyl) - 4 - (21 - furfurylidene) - oxazol - 5 - one; those as herbicides: 2-phenyl-4-(a -naphthyl methylene)-oxazol-5-one or 2-phenyl-4-(9-anthryl methylene)-oxazol-one; those for combating plant virus diseases 2-phenyl-4-(phthalidylidene)-oxazol-5-one and to a lesser extent 2-phenyl-4-(benzilidene)-oxazol-5-one, 2-phenyl-4-(2-naphthyl methylene)-oxazol-5-one, 2-phenyl-4-(21-furfurylidene)-oxazol-5-one or 2-phenyl-4-(21-thienylidene)-oxazol-5-one; and the compound useful for cultivating fungi is 2-phenyl-4-(21-furfurylidene)-oxazol-5-one. The compositions may take the form of dusts, sprays or wettable powders.  The dusts may be compounded by the use, as a carrier, of talc, clay, silica, carbon, fuller's earth or kieselguhr and may or may not be treated with oil to improve adhesivity to the plant surface.  The wettable powders comprise the active ingredient mixed with a wetting and/or suspending agent and/or further inert carriers as above listed, and/or other additives, e.g. sodium phosphate, sodium polyphosphate or cellulose ethers.  The sprays may be solutions or dispersions of the active ingredients inorganic liquids or aqueous dilutions of wettable powders or emulsified concentrates containing the active ingredients. Suitable carriers for spray fungicides are petroleum oils boiling at 275-575 DEG  F. or at 575-1000 DEG  F. if the unsulphonatable residue is at least 75 per cent; and for herbicidal sprays the carrier may comprise kerosine, gas oils, lubricating oils or extracts of petroleum fractions with liquid sulphur dioxide or furfural.  Specified surface-active agents present in the compositions are condensation products of ethylene oxide and oleyl alcohol, abietic acid or p-octylphenol.

Title: Improvements in moving picture films containing sound records, and method for developing such films
IPC: G03D3/12
Filed: 1931-08-10
Abstract: 387,703. Combined sound and picture films. TANATAR, M., 2, Rue Auguste Vitu, Paris. Aug. 10, 1931, No. 22599. [Class 40 (ii).] In developing motion-picture films of the kind comprising a single film bearing sound and image records, one or more of the records whose time of development is shorter is or are covered by an impermeable substance and the partially protected film is then immersed in a bath of developer. As shown in Figs. 1 and 2, the sound record 4 of a film 1 is covered by a rubber band 5 against which it is pressed by a second band 6, and is passed through a developing tank 2. The band 6 passes around spools 7 having at one end sprockets to engage the film at one side, the sprockets also engaging recesses 10 in a band 9 passing around spools 8 carrying the band 5. From the tank 2 the film, separated from the band 5, passes to a second developing tank 3, where the sound record is developed and the development of the picture record is completed. Rollers 13 and bands 14 guide the film in the tank 3. The level of the developer in the two tanks is regulated by levels 18 to control the development. From the tank 3 the film passes to washing, fixing, &c. vessels. A wiper 11 cleans the band 5. In a modification, a gummed strip is applied to the film to cover the sound record, such strip being suitably removed after partial development.
